Created attachment 134397 [details] output of konqi Application: akonadiserver (5.10.3) Qt Version: 5.9.7 Frameworks Version: 5.55.0 Operating System: Linux 4.12.14-lp151.28.87-default x86_64 Distribution: "openSUSE Leap 15.1" -- Information about the crash: - What I was doing when the application crashed: I programmed the mail to be archived automatically within one only archive. During the archiving procedure, akonadi crashed twice, giving backtrace twice. The archiving however did proceed correctly to the end. This kind of crash did not happen beforehand and appeared now that it seems a patch was brought in to avoid the crashing of Akonadi after changing settings in archival function (honi soit qui mal y pense). - Unusual behavior I noticed: High system load (on a core i5 ironlake, which is admittedly old but does not experience 100 % Core load on one or two processors so often. Temperature of CPU quite high, but emergency shutdown onlz sometimes. The crashes do apparently not stop the archiving itself that has normal size and content. I did prior to the archival aconadictl fsck, vacuum and restart. EXPECTED RESULT show run without segfaulting ADDITIONAL INFORMATION As the output of konqi exceeds the length limit I join an attachment.
